I used this plugin “jQuery Migrate”.
https://wordpress.org/plugins/enable-jquery-migrate-helper/
On the plugin settings page set “jQuery Version” to “Legacy 1.12.4-wp”.
I think will fix the error.

Strategically make JavaScript and CSS external to utilize browser caching.

Details from Yahoo!

Using external files in the real world generally produces faster pages because the JavaScript and CSS files are cached by the browser.

JavaScript and CSS that are inlined in HTML documents get downloaded every time the HTML document is requested. This reduces the number of HTTP requests that are needed, but increases the size of the HTML document.

On the other hand, if the JavaScript and CSS are in external files cached by the browser, the size of the HTML document is reduced without increasing the number of HTTP requests.

mostly this kind of error is caused by missing an .htaccess file in your root wordpress directory ,
Please check that
if . htaccess no available create a new on in root of wp and past that default Wordpress configuration.
